Question
QUESTION: Dear Cal

Is marble flooring allowed on Airports runways?.

Thanks
Prashant

ANSWER: No. Airport surfaces start with bare earth or grass. The next step is to pave them with asphalt (macadam) or concrete. Some military airports use pierced steel planking (PSP). That is for short term operations.

QUESTION: Dear Cal

Thanks.

Will marble flooring be not recommended from the cost point of view Or Security regarding plane landing or departure?.

Thanks
Prashant

Answer
Do a tiny bit of thinking about paving a runway with marble. How much would you need? How thick would be required to land a 747? Marble is too expensive, not strong enough, cannot be laid in large enough area and on and on. For a century, macadam and concrete have proven to be the best paving for a runway.

Expertise

Questions about the Douglas C-133 Cargomaster, its history, operations and technical information. I wrote and published the definitive history of the C-133, Remembering an Unsung Giant: The Douglas C-133 Cargomaster and Its People. Someone has done a good job of extracting material from my book for the article about the C-133 on AllExperts. I AM NOT an expert on educational opportunities in India or other countries and request that such questions be directed elsewhere. I will not answer such questions because I do not have the knowledge to do so adequately.

Experience

I accrued 1,837 hours as a C-133 navigator out of a total of 6,738 flying hours in the USAF. Twelve years of that time were as a crew member, the other years were in various training assignments and as a USAF intelligence officer. My flying experience includes time in the B-52H, C-141, C-133, AC-130, C-130 and the C-5A. I have considerable knowledge in general aviatio history.
